KESTD-Ronin

What is it?

KESTD-Ronin is a lightweight, experiment friendly and cross platform game engine developed by Mario Sieg.

What is the usage?

The engine and the integrated editor "AutoTec" can be used to create fully features 3D apps, simulations and games. The engine is designed to be very easy to use and flexible - hence "experiment friendly", because it is also often used to test algorithms, rendering techiques or physics. Besides from games it can also be used to create visualizations of all kinds; for demos, architecture and art. Also it is currently used by me for various projects and demos.

What languages?

The main engine is written in modern C++ 20. For general and gameplay scripting C++ or the very flexible Lua language can be used.

There is still some code missing. I'm currently making a big cleanup and refractor then the code will appear!
